LAMP-CLEANER.

Specification of Letters Patent.

Patented J an. 26, 1915.

Application filed April 28, 1914. Serial No. 834,921.

ToaZZ whom it may concern:

Be it known that I, WALLACE D. BOWIE, a

citizen of the United States, and a resident miners calcium carbid lamps.

Another object in view is to provide a cleaning device easily applied and removed and also easily and quickly operated at any time for cleaning the gas outlet tube 111 lamps using calcium oarbid.

In carrying out the objects of the invention a lamp of any desired kind may be provided or used. The lamp is provided with the usual gas outlet tubes carrying a burner structure provided with a small opening or tip through which the gas passes before it is ignited. Associated with the gas tube and the tip are two members, namely, a retaining member and a needle connected with the retaining member. These are arranged so that the burner structure may be threaded on to the retaining member and the needle may be extended through the gas outlet tip when the burner is screwed or turned until it occupies a predetermined position, whereby the gas outlet tip is cleaned.

In the accompanying drawingsFigure l is a side view of a miners lamp with an embodiment of the invention applied thereto; Fig. 2 is a section through Fig. 1 approximately on line 22; Fig. 3 is a new similar to Fig. 2 except that a retaining member is shown in section; Fig. A is an en larged sectional view through Fig. 3 approximately on line 4-l.

Referring to the accompanying drawings by numeral, 1 indicates a miners lamp of any desired kind provided with a carbid reservoir 2 and a water reservoir 3. A wa ter and gas tube 1 is also provided arranged in line with tube 5 in which a suitable wire 6 is placed designed to act in the usual manner for the cleaning of tubes 4 and 5, and also for better regulating the passage of water and gas. Arranged above the carbid chamber 2 is a gas chamber 7 into which 'to its ignition. opening 15 from becoming clogged or projects a tube 8. The tube 8 is designed to accommodate the retaining member 9, and also the end of the reflector 10. The retaining member 9 is provided with a bifurcated portion 11 which is preferably somewhat resilient, and which'is forced against tube 4 when the device is in operation. The bifurcated portion 11 merges into a tubular member 12 threaded exteriorly for receiving the interiorly threaded extension 13 of reflector 10. The tubular 1nember12 is formed with an enlargement 12 which snugly fits the tube 8 so that the gas must pass through the tubular member as the same passes to the discharge outlet tip 14.

Arranged in the tubular extension 13 is a gas outlet tip 14 having a comparatively small aperture 15 arranged therein through which the gas passes immediately previous In order to prevent the stopped up a needle 16 is provided which extends through the tubular part 12 of member 9, and is connected at 17 in any desired manner, as for instance by solder to memher 9. The connection at 17 is preferably such as to position needle 16 substantially central of the aperture 18 in tubular mem ber 12. A bifurcated portion 11 is provided with shoulders 19 and 20 which snap over the inner ends of the tube 8 when member 9 is in operative position as shown in Figs. 2 and 3. This prevents a reverse movement of member 9 while the engagement of the ends of the bifurcated portion 11 prevents the rotation of member 11 together with the tubular part 12.

In operation after the lamp has been properly filled reflector 10 is rotated until the end of needle 16 has left a suflicient opening in tip 14: to allow the proper amount of gas to escape for producing the desired flame. If for any reason a particle of dirt or foreign matter should clog the opening 15 in the tip 14, reflector 10 may be rotated and thereby the tip 14 caused to telescope over the needle, whereby the opening 15 will be cleaned. A reverse movement will bring the reflector back to its original position, where upon the lamp may be again lighted. Under some circumstances, as for instance when there is only a small amount of foreign matter in the opening or passageway 15 a slight back and forth movement of the reflector will cause the foreign matter to be dislodged and the passageway may thus be cleaned without shutting oil the gas entirely.

What I claim is V V 1. In a device of the character described, means for producing a gas, a tube projecting into said means, a retaining member arranged in saidtube, said retaining member 7 taining member, and an outlet tip rigidly secured to the'refiector, said outlet tipbeing provided with an aperture in line with said needle, whereby.when the reflector is rotated in one direction said tip will tele scope over said needle, and when rotated in the opposite directionwill move from said needle.

p 2. In a device of the character described,

a lamp structure including means for the production of gas, a gas discharge tube extending into the casing of the lamp, a re- Copies of this patent may be obtained for taming member arranged in said tube and fitting the same so that gas must pass through said retaining member, said retainingmember being provided with a 1ongitudinal bore, and with abifurcated end, said bifurcated end being formed with shoulders fitting against the end of said tube, whereby the retaining member is held in position, means engaging saidbifurcated end for preventing said shoulder leaving said tube, a needle connected with said retaining member and extending through the bore therein, said needle projecting beyond said retaining member, a discharge tip provided with an aperture in llne wlth said bore, and a rotatable member supporting said tip, said rotatable member being threaded onto said retaining member, whereby when the rotatable member is moved the same will cause the tip to move longitudinally of said needle and the. aperture therein to be cleaned thereby. l V

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
